<p>A method for vaporizing particulate material and condensing it onto a surface to form a layer provides a quantity of first particulate material in a first container and a quantity of second particulate material in a second container spaced apart from the first container, the first and second containers respectively having first and second openings. The first particulate material is transferred through the first opening in the first container into a manifold and vaporized in the manifold. The second particulate material is transferred through the second opening in the second container into the manifold and vaporized in the manifold, whereby the first and second vaporized particulate materials are mixed. The mixed vaporized materials are delivered from the manifold to the surface to form the layer.</p> |
